⚠️ Risk & Real-World Impact
Worst Case
Complete system compromise allowing attackers to install malware, steal data, encrypt files for ransomware, and pivot to other network systems.
Likely Case
Remote code execution leading to data theft, unauthorized access to stored files, and potential deployment of cryptocurrency miners or botnet malware.
If Mitigated
Limited impact if systems are isolated behind firewalls with strict network segmentation and access controls.
🎯 Exploit Status
The vulnerability description suggests remote exploitation without authentication, though specific exploit vectors are unspecified.

🔧 Temporary Workarounds
Network Isolation
allRestrict network access to Synology devices to only trusted IP addresses
Configure firewall rules to block all external access to Synology management ports (typically 5000, 5001)
Disable Unnecessary Services
linuxTurn off any unnecessary services or plugins that might expose the vulnerable daemon
Go to Package Center > Installed > Select unnecessary packages > Uninstall
🧯 If You Can't Patch
- Immediately isolate affected systems from internet and untrusted networks
- Implement strict network segmentation and monitor for suspicious activity
🔍 How to Verify
Check if Vulnerable:
Check current version in Control Panel > Info Center > DSM/BSM versionCheck Version:
ssh admin@synology_ip 'cat /etc.defaults/VERSION' or check web interfaceVerify Fix Applied:
Verify version is BSM 1.1-65374+ or DSM 7.2-64570-4+, 7.2.1-69057-6+, or 7.2.2-72806-1+📡 Detection & Monitoring
